The SSD SCX10 II Diamond Pro Rear Axle Case is the first of its kind. A hybrid design featuring a plastic center pumpkin, with heavy metal axle tubes, this axle weighs in at 97 grams for just the axle assembly alone and will help to increase unsprung weight for increased stability and improved overall performance. It is a direct upgrade for the AR44 axle housing, and eliminates the rear lockouts for a more scale appearance.
